The DECAPs Archive is an implementation of the full survey release of the DECAM Plane Survey. DECaPS is a five-band optical and near-infrared survey of the southern Galactic plane with the Dark Energy Camera (DECam) at Cerro Tololo. The survey is designed to reach past the main-sequence turn-off at the distance of the Galactic center through a reddening E(B-V) of 1.5 mag, with a typical single-exposure depth of 23.7, 22.8, 22.2, 21.8, and 21.0 mag in the grizY bands, and seeing around 1''. The footprint covers |b|<4 degrees, 5 > l > -120 degrees (essentially the low latitude Galactic plane south of delta < −30 degrees), a total of about 1000 square degrees. DECaPS simultaneously solves for the positions and fluxes of all the sources in each image, delivering positions and fluxes of roughly two billion stars with up to 5 mmag repeatability. Most of these objects are highly reddened and deep in the Galactic disk, probing the structure and properties of the Milky Way and its interstellar medium. Schlafly et al. 2017describes the survey.
